Two chlorine sensor measuring principle

Residual chlorine sensors are based mostly on different measuring rules, may be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for digital pressure gauge of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode covered with a layer of fuel permeable skinny movie composition. The remaining chlorine within the tested answer diffuses to the cathode via the diaphragm, and the cathode and anode are appropriate the polarization voltage can scale back the residual chlorine on the cathode, and these chemical reactions happen in the residual chlorine within the measured solution chlorine is proportional to the current.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to type a microbattery measurement system. During measurement, a stable electrical potential is maintained on the measuring finish of the electrode, and totally different elements are produced underneath this electrical potential generate completely different, well linear present intensities.
polarographic sensor is characterized by:
Sensitive reaction, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for all kinds of media, film is not simple to break, air pollution resistance

fixed voltage type sensor is characterised by:
With stable zero efficiency, to make sure accurate and dependable measurement

Simple construction, straightforward to scrub

It is suitable for measuring residual chlorine, chlorine dioxide and ozone in water

Correction:
Zero point correction

Zero correction with chlorine-free water

Slope correction

Actual measurements are made in a transportable or laboratory setting

Make alignment

Matters needing attention:
PH must be managed at 5-8pH

The circulate should be managed at 60-80L/H

The stress is within 4bar

Residual chlorine sensors are primarily based on completely different measuring principles, may be divided into diaphragm polarographic sensor and fixed voltage sensor.
Used for continuous monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode lined with a layer of gas permeable thin film composition. The remaining chlorine within the examined answer diffuses to the cathode via the diaphragm, and the cathode and anode are applicable the polarization voltage can scale back the residual chlorine at the cathode, and these chemical reactions occur in the residual chlorine within the measured resolution chlorine is proportional to the current.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to kind a microbattery measurement system. During measurement, a secure electrical potential is maintained at the measuring finish of the electrode, and completely different elements are produced under this electrical potential generate completely different, nicely linear present intensities.
polarographic sensor is characterised by:
Sensitive response, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for all types of media, film is not easy to wreck, pollution resistance

constant voltage sort sensor is characterised by:
With stable zero performance, to make sure correct and reliable measurement

Simple structure, simple to scrub

It is suitable for measuring residual chlorine, chlorine dioxide and ozone in water

Correction:
Zero point correction

Zero correction with chlorine-free water

Slope correction

Actual measurements are made in a portable or laboratory setting

Make alignment

Matters needing attention:
PH should be managed at 5-8pH

The flow ought to be controlled at 60-80L/H

The stress is inside 4bar
